Leverage the full potential of Test generation by following these design considerations.

## Test generation records and components {#tg-summary__section_xg4_dvz_hdc}

Test generation application has the following records and components.

Test
:   A test is a logical grouping of related automated test steps that verify some functionality or feature. Each test is a record in the Test \[sys_atf_test\] table. Test designers typically create a test to verify
    one feature or a group of related features.

Test step
:   A test step combines a step configuration with the runtime test data necessary to run a step. The test step always specifies the order in which it runs in the test. Test steps have their own related list of step
    results. Each test step is a record in the Test Step \[sys_atf_step\] table that specifies a test action, the step configuration, and an execution order. Test designers add test steps to tests to verify functionality.

## Exceptions {#tg-summary__section_gkz_xct_rdc}

* Test generation doesn't support the following test step categories:
  * Custom UI
  * Lists
  * Service Catalog in Service Portal
  * Forms in Service Portal

* Test generation doesn't support scripts and custom scripts.
